No grasps show after calculation about dex-net HOT 13 CLOSED

I had the same problem, but I didn't have your error "Display grasps failed".
But you could try what I did and see if it solves yours as well.
I solved mine by changing the lines of code in dex-net/src/dexnet/visualization/visualizer3d.py in the function to visualize grasps from:

mlab.points3d(g1_tf.data[0], g1_tf.data[1], g1_tf.data[2], color=endpoint_color, scale_factor=endpoint_scale)
mlab.points3d(g2_tf.data[0], g2_tf.data[1], g2_tf.data[2], color=endpoint_color, scale_factor=endpoint_scale)
mlab.plot3d(grasp_axis_tf[:,0], grasp_axis_tf[:,1], grasp_axis_tf[:,2], color=grasp_axis_color, tube_radius=tube_radius)

to ->
points = [(x[0], x[1], x[2]) for x in grasp_axis_tf]
Visualizer3D.plot3d(points, color=grasp_axis_color, tube_radius=tube_radius)

from dex-net.

It works!
Thanks for your suggestion!

Nevermind, I just set the repo visibility to public and changed the README so it is clear where the code comes from.
You can find it here: https://github.com/SilviaSapora/dex-net-silvia. Please email any questions at silvia.sapora at gmail dot com. I'm very busy at the moment, but I'll do what I can to reply to your questions!

Hi SilviaSapora.
You made a great contribution to the robotic grasp community through your thesis: "Grasp Quality Deep Neural Networks for Robotic Object Grasping". I recently have researched on Dex-Net 2.0 but I am facing a lot of troubles with installation issues.
I wonder if you are still active on this account or is there any way to communicate with you.
I need your experience about Dex-Net.

Hope to hear from you.

Hi @nguyenquanghuyvub, thank you for your comments, I'm very happy you found my thesis helpful.
I just sent you and invite for my version of the dex-net repository.
I didn't make it public as I didn't fork it but just copied everything at the time.
Anyway, in there you can find an install_history.txt file that contains almost all the commands I ran to make dex-net and its dependencies work from a completely new Linux install.
There is some stuff still missing I believe, and it might not work with newer versions of Linux, but I hope you can find some of it helpful.

I am sorry, but I have not seen any invitation to your repos yet.
Would you please verify again.
Thank you.

1- I'm using Python 2.7.15rc1
2- I believe I did successfully install the mayavi library(mayavi2), but I can't really remember how. If I run 'mayavi2 --version' I get: Mayavi 4.6.2
I hope this is useful
